Cov tshuaj tsuag ntsev simulates ntev - lub sij hawm raug rau cov dej qab ntsev ib puag ncig los ntawm kev tso cov qauv PCBA rau hauv chav kuaj tswj uas tau ntim nrog cov tshuaj ntsev ntsev, feem ntau yog sodium chloride (NaCl). Thaum lub sij hawm kev xeem, cov rooj sib txoos tau raug rau cov ntsev nruam ntawm qhov ntsuas kub thiab lub sijhawm, tso cai rau cov tuam txhab tshuaj ntsuam xyuas qhov tsis kam ntawm cov ntaub ntawv, cov khoom tiav, cov pob qij txha, thiab cov txheej txheem tiv thaiv corrosion.
Hauv PCBA kev tsim khoom, kev kuaj tshuaj ntsev ntsev feem ntau yog siv los txheeb xyuas qhov ua tau zoo ntawmPCB nto tiavxws li ENIG, HASL, lossis ENEPIG, thiabconformal txheejthiab enclosure tiv thaiv. Tsis zoo corrosion kuj tuaj yeem ua rau oxidation ntawm tooj liab kab, degradation ntawm cov pob qij txha, nce kev tiv thaiv, thiab hluav taws xob tsis ua hauj lwm.
Cov sijhawm xeem sib txawv nyob ntawm daim ntawv thov thiab cov qauv kev lag luam, txij li 24 teev mus rau ntau pua teev. Tom qab kev sim, PCBA cov qauv raug tshuaj xyuas rau cov cim ntawm corrosion, discoloration, delamination, los yog kev ua haujlwm degradation. Kev ntsuam xyuas hluav taws xob feem ntau yog ua los xyuas kom meej tias lub rooj sib txoos tseem ua tau raws li qhov yuav tsum tau ua.
PCBA tshuaj tsuag ntsev yog qhov tseem ceeb tshwj xeeb rau cov khoom siv hluav taws xob hauv tsheb, cov khoom siv them nyiaj, cov tshuab hluav taws xob sab nraum zoov, thiab cov ntug dej hiav txwv lossis siab - cov av noo ib puag ncig. Los ntawm kev ua cov tshuaj tsuag tshuaj ntsev, cov tuam txhab tsim khoom tuaj yeem txhim kho cov khoom lag luam kom ruaj khov, txo qhov kev pheej hmoo tsis ua haujlwm, thiab ua kom ntev - lub sij hawm cia siab rau hauv kev ua haujlwm corrosive.
